Astru - In-Ear Monitors

The Meze Audio ASTRU is a high-performance in-ear monitor designed for audiophiles seeking flagship-level sound in a refined single-driver design. Built around a custom 10 mm dynamic driver with a multilayer gold-coated diaphragm, ASTRU delivers fast transient response, extended treble, and natural warmth while maintaining excellent control and detail.

Each housing is CNC-machined from solid titanium, providing durability, low resonance, and long-term comfort. The acoustic design is carefully tuned to achieve the depth, imaging, and resolution often associated with multi-driver earphones while keeping the coherence of a single driver.

ASTRU includes a premium detachable cable with a balanced 4.4 mm termination, along with a 3.5 mm adapter for wider compatibility. Multiple ear-tip sizes and protective carry accessories make the earphones suitable for portable use as well as high-end listening setups.

Designed for serious listeners, the ASTRU combines advanced materials, precision manufacturing, and Meze Audio’s focus on comfort and musicality to deliver a rich, immersive listening experience.
